Soon after releasing iTunes 10.2.1 update, Apple has just released iOS 4.3 final for iPhone 4/3GS, iPod Touch 4G/3G, iPad 2/1st Gen & Apple TV 2G. The build of iOS 4.3 final is same as iOS 4.3 GM which was released last week for developers only. To update your iDevice to iOS 4.3, just connect it to iTunes and hit the Update button or use the direct download links to iOS 4.3 IPSWs after the break.

What's New in iOS 4.3:

Much Faster Safari: iOS 4.3 Mobile Safari app is now powered with a new JavaScript engine called Nitro which makes web-browsing twice as fast as before. Its the same JavaScript engine that powers the desktop version of Safari.

Improved AirPlay: The AirPlay feature which was introduced by Apple in iOS 4.2 has been dramatically improved in iOS 4.3. Now you can AirPlay songs, movies or photos from 3rd party apps directly to your Apple TV.

iTunes Home Sharing: Now with Home Sharing feature of iOS 4.3, you can play any song or video on your iPhone, iPod Touch or iPad that is stored on your desktop's iTunes library. Ofcourse you will be needing an active Wi-Fi connection and Apple ID for authentication.

Personal Hotspot: With Personal Hotspot feature of iOS 4.3, you can turn your iPhone 4 into a Wi-Fi router which can share its internet-connection with 3 Wi-Fi enabled devices at the same time.

For Jailbreakers & Unlockers:

Those iPhone users who rely on unlock, should stay away from these stock iOS 4.3 IPSWs. Upgrading your iPhone 4 to stock iOS 4.3 will upgrade its baseband to 05.10.01. Similarly, restoring iOS 4.3 stock IPSW on your iPhone 3GS will upgrade its baseband to 05.16.00. At this moment, there is no exploit available that could crash and unlock any of these basebands. We will update you as soon as there will be an unlock available for these basebands. Stay tuned!
